APPLICATION NOTES Driving Capacitiv Loads Th SGM86x can dirctly driv pf in unity-gain without oscillation. Th unity-gain followr (buffr) is th most snsitiv configuration to capacitiv loading. Dirct capacitiv loading rducs th phas margin of amplifirs and this rsults in ringing or vn oscillation. Applications that rquir gratr capacitiv driv capability should us an isolation rsistor btwn th output and th capacitiv load lik th circuit in Figur. Th isolation rsistor R ISO and th load capacitor C L form a zro to incras stability. Th biggr th R ISO rsistor valu, th mor stabl V OUT will b. Not that this mthod rsults in a loss of gain accuracy bcaus R ISO forms a voltag dividr with th R LOAD. V IN SGM86 R ISO V OUT Figur. Indirctly Driving Havy Capacitiv Load An improvmnt circuit is shown in Figur. It provids DC accuracy as wll as AC stability. R F provids th DC accuracy by conncting th invrting signal with th output. C F and R Iso srv to countract th loss of phas margin by fding th high frquncy componnt of th output signal back to th amplifir s invrting input, thrby prsrving phas margin in th ovrall fdback loop. C L Powr-Supply Bypassing and Layout Th SGM86x family oprats from ithr a singl +.5V to +5.5V supply or dual ±.5V to ±.75V supplis. For singl-supply opration, bypass th powr supply V DD with a.µf cramic capacitor which should b placd clos to th V DD pin. For dual-supply opration, both th V DD and th V SS supplis should b bypassd to ground with sparat.µf cramic capacitors..µf tantalum capacitor can b addd for bttr prformanc. Good PC board layout tchniqus optimiz prformanc by dcrasing th amount of stray capacitanc at th op amp s inputs and output. To dcras stray capacitanc, minimiz trac lngths and widths by placing xtrnal componnts as clos to th dvic as possibl. Us surfac-mount componnts whnvr possibl. For th oprational amplifir, soldring th part to th board dirctly is strongly rcommndd. Try to kp th high frquncy big currnt loop ara small to minimiz th EMI (lctromagntic intrfacing).

Indirctly Driving Havy Capacitiv Load with DC Accuracy For no-buffr configuration, thr ar two othrs ways to incras th phas margin: (a) by incrasing th amplifir s gain or (b) by placing a capacitor in paralll with th fdback rsistor to countract th parasitic capacitanc associatd with invrting nod. V SS Figur. Amplifir with Bypass Capacitors Grounding A ground plan layr is important for SGM86x circuit dsign. Th lngth of th currnt path spd currnts in an inductiv ground rturn will crat an unwantd voltag nois. Broad ground plan aras will rduc th parasitic inductanc.
